Microprogrammed Control in Problem-Oriented Languages

The application of microprogramming to problem-oriented languages is described in terms of a simulated analog system on a digital computer. Microprogramming facilitates the development of a problem-oriented machine code, which can be simply generated from the problem-oriented source language by simple translation. In the system described a problem defined by differential equations is drawn up in the form of an analog diagram. The diagram is coded into an analog-oriented source language which is converted by translation into the analog machine code. The system also allows the machine assembly code to be freely used with the analog input in coding the supervisory and interrupt facilities that are incorporated in the overall system design.
